Application preloading method and device, storage medium and terminal

Abstract

The embodiments of the disclosure provide an Application (APP) preloading method and device, a storage medium and a terminal. The method includes that: when an APP preloading event is detected to be triggered, an APP to be preloaded is determined; whether a first APP which is being started in foreground exists or not is judged; and if NO, the APP to be preloaded is preloaded. According to the application, with adoption of the technical solution, not only low speed and non-fluency, caused by preloading the APP, for starting of the APP in foreground may be effectively avoided, but also a speed of preloading the APP to be preloaded may be effectively increased, so that a speed of starting the APP to be preloaded may be increased.

The invention claimed is: 
     
       1. A method for Application (APP) preloading, comprising:
 determining, in response to detecting that an APP preloading event is triggered, an APP to be preloaded; 
 judging whether a first APP which is being started in foreground exists or not; and 
 in response to determining that the first APP which is not being started in foreground preloading, based on a preloading Activity stack which is pre-created in an Android system, an APP interface corresponding to the APP to be preloaded, a boundary coordinate of the preloading Activity stack being located outside a coordinate range of a display screen; 
 migrating, in response to receiving an instruction for starting a target APP in the APP to be preloaded, an APP interface corresponding to the target APP in the preloading Activity stack to the display screen for displaying; and 
 sending a falsified focus notification to the APP to be preloaded, and keeping performing continuous drawing and displaying updating on the APP interface corresponding to the APP to be preloaded in a preset time period based on the falsified focus notification, so that when the APP to be preloaded is started, a home page of the APP or other interfaces operable for the user is directly accessible. 
 
     
     
       2. The method of  claim 1 , further comprising:
 forbidding, in response to determining that the first APP which is being started in foreground exists, preloading the APP to be preloaded. 
 
     
     
       3. The method of  claim 1 , wherein judging whether the first APP which is being started in foreground exists or not comprises:
 judging whether the first APP in a starting stage exists in foreground or not, wherein the starting stage is from an initial starting moment of the first APP to a complete display moment of a display interface of the first APP. 
 
     
     
       4. The method of  claim 1 , further comprising:
 during a process of preloading the APP to be preloaded, terminating preloading the APP to be preloaded and releasing a preloaded starting resource corresponding to the APP to be preloaded, in response to detecting that a starting event of a foreground APP is triggered. 
 
     
     
       5. The method of  claim 4 , wherein releasing the preloaded starting resource corresponding to the APP to be preloaded comprises:
 releasing an active window exclusive lock occupied by the APP to be preloaded. 
 
     
     
       6. The method of  claim 1 , wherein
 the migrating the APP interface corresponding to the target APP in the preloading Activity stack to the display screen for displaying comprises: 
 migrating a task stack corresponding to the target APP in the preloading Activity stack to a top of an APP Activity stack; and 
 updating size information, configuration information and visibility of the task stack to display the APP interface corresponding to the target APP in the display screen. 
 
     
     
       7. A device for Application (APP) preloading, comprising:
 a memory for storing a computer program; and 
 a processor, wherein the processor is configured to execute the computer program to implement steps of: 
 determining, in response to detecting that an APP preloading event is triggered, an APP to be preloaded; 
 judging whether a first APP which is being started in foreground exists or not; and 
 in a case that the first APP which is not being started in foreground, preloading, based on a preloading Activity stack which is pre-created in an Android system, an APP interface corresponding to the APP to be preloaded, a boundary coordinate of the preloading Activity stack being located outside a coordinate range of a display screen; 
 migrating, in response to receiving an instruction for starting a target APP in the APP to be preloaded, an APP interface corresponding to the target APP in the preloading Activity stack to the display screen for displaying; and 
 sending a falsified focus notification to the APP to be preloaded, and keeping performing continuous drawing and displaying updating on the APP interface corresponding to the APP to be preloaded in a preset time period based on the falsified focus notification, so that when the APP to be preloaded is started, a home page of the APP or other interfaces operable for the user is directly accessible. 
 
     
     
       8. The device of  claim 7 , wherein the processor is further configured to execute the computer program to implement a step of:
 forbidding, in response to determining that the first APP which is being started in foreground exists, preloading the APP to be preloaded. 
 
     
     
       9. The device of  claim 7 , wherein the processor is configured to execute the computer program to further implement a step of:
 judging whether the first APP in the starting stage exists in foreground or not, wherein the starting stage is from an initial starting moment of the first APP to a complete display moment of a display interface of the first APP. 
 
     
     
       10. The device of  claim 7 , wherein the processor is further configured to execute the computer program to implement a step of:
 during a process of preloading the APP to be preloaded, terminating, in response to detecting that a starting event of a foreground APP is triggered, the preloading the APP to be preloaded and releasing a preloaded starting resource corresponding to the APP to be preloaded.
